of thread and yarn or Woven fabrics, the

materia-l to` be dyed being immersed in a bodyor bath .of liquid dye containedin a tank or reservoir, and agitated by air forced into the bottoni of the tank, the dye liquor being at the same time heated and preferably moved progressively, so that the ma` terial is caused to pass over the air inlets provided in the bottom of the tank and is thereby thoroughly impregnated with the dye liquor; theair Aascending through the heated dye `liquor notonlyagitating the liquor but bringing about a chemical re-` action 1n such manner that a fast color 1s imparted to the material.

` Theinvention has for its-object to enable an apparatus of the generaljcharacter indi`- cated to be operated with the greatest possible economy ofheat and dye liquor, and 4according to this invention the apparatus is so devised `that the dye liquor is heated While air is passing through it and that the heated air and vapor rising from the dye ,liquor are returned tothe bottom of the tank, so that practically no heat is lost, and the dye material which rises with the vapor isreturned tothe bath( y y In order that the said invention lmay be clearly understood and readily carried into effect `the samewill now be described more fully drawings, in which y y Figure l represents a planview, Fig. 2

Fig. 8 repreresents aperspective-view of part of the apparatus.` Fig. 5 is a plan view of one of the twyers which may be used with the apparatus as hereinafter explained. Fig. 6 represents a section on liner of Fig. t. Fig. 7 represents a section on line 7 of Fig.` 5. Fig. 8 is a detail plan view show,

ing the pipe connections with the twyers more clearly shown than in the preceding'` with reference Y to the accompanying ligures. The samereference characters refer to the same parts in all the figures.

a represents a tank or reservoir which is preferably of elliptical trough formation although'k it may be of any other suitable form. The tank as here shown is of the `general form represented by the drawings of `the prior United, States Patent No.

864,3@ dated August 27, 1907, and is provided with paddle wheels Z) revolved by shaftsA c journaled `in bearings above `the tank, the wheels `being rotated simultaneously in opposite directions by mech- `anism which may be similar to that shown lb'y the drawings forming part of the afore- `saidfprior patent, so that a body of dye liquor in saidtank is caused' to circulate therein. I have not represented the mechanism forrotating the paddle wheels, the same forming no part of the present invention.` rI`heftank `is provided with a closely fitting top d and with paddle boxes e located over the, paddle wheels, said top and bores forming a practically air tight cover which closes thel tank and prevents loss of dye liquor b y evaporation therefrom. The end portions d of the cover are hinged and yadapted to be raised to afford access to the tank. y

In the bottom of thetank are twyers f having narrow elongated `air outlets g adapted to discharge air upwardly into the body of dye liquor. rIhese twyers are connected by conduits or outlet pipes z', j, `with the outlet 7c of an airpump c which forces air simultaneously through all the twyers. The inlet 7c? of the air pump is connected by conduits or suction pipes m with an opening in thecover of the tank, and preferably situated in that part of the cover formed by the paddle boxes c. The air pump therefore draws air from the top of the tank and returns the said air through the twyers f to the bottom of the tank so that a continuous circulation of thelsaid air is maintained. i j

fIn this embodiment of my invention Iemploy the means next described for heating the dye liquor :-`-Each ofthe twyers f is subfdividedby apartitionf (Figs. 5, 6 and 7) intotwo chambers,` one of which commu#` `nicates with the air outletg and conduit t'. The, other of said chambers communicates with a .steam conduit oandis provided with :a'narrow elongated steam outlet p located beside the air outlet g and adapted to dis-v l charge steam upwardly into thebody of dye liquor. The steam conduits oentering the several tWyers are branches of a steam conduit which, as here shown, includes a dye receptacle or drum fr communicating with" steam conduits or pipes g, g", the pipepg admitting steam from the source-ofsupply to the drum While the pipe g conducts steam. I from the drum to the branch pipes o enter` liquor or `material into the tankin a thoroughly mixed condition. To this end the drum is provided With a dye inlet or funnel tV for the reception of the `dye liquor, said funnelhaving aneck t provided With a, valve a. The pipes gr andy are provided res pectively- With valves o and o. When the valve uis closed, and the .valves U fUppare opened, the drum 11 is simply a part of the steam conduit which supplies steam to the 'tWyer outlets p, this being the normal condition during the dyeing operation. When more dye liquor is to be introduced, the valves 'u `and fo are closed and the valve u .yisopened The drum r is then charged with dye liquor after Which the valve a is closed and the valves o o" are opened.. The steam pressure noW forces the dye liquor from the drum through the steam outlets p into the gtank so that the dye liquor in the tank may be strengthened at any time by fresh` dye materials Without opening the top of the tank, the dye material being uniformly distributed by the steam.

The steam supply should be sufficient to 4''1naintainthe dye liquor in the tank at a temperature of substantially 212 F. The vaporgiven off by the dye liquor at this temperature carries With it more or less of ,j the dye material Which would be Wasted if the vapor Were allowed to escape. The mixture of steam or vapor, air and particles of dye liquor collected at the top of the tank is returned to the tank by the pump 7c so that there is no considerable loss eitherof dye or heat.

lThe air cooperates with the heated dye liquor in quickly imparting a fast color to the material inserted therein.

1 i I do .not limit myself to 'van apparatus em- Abodying an endless tank and means such as the vpaddle Wheels Z2 for circulating the dye liquor.. v

@The tank may lbe of any other desired a j form andother means may be employed for circulating the liquor or the circulating means may be omitted.

Copies of this patent may be obtained for ive cents each, by addressing the. Commissioner fof It Will be observed that the heating steam is discharged into the bath ofgdye liquor contained inthe tank, simultaneously With the agitating air, so that the steam per- W'hat ll claim and desire to secure by Letters Patent is :e l
